A height gauge has a touch signal probe provided on a slider vertically movably supported on a support for the purpose of measuring the dimensions or the like of an object by bringing the probe into contact with the object. A rack is formed on the support, and a driving shaft is disposed on the slider, the driving shaft having a pinion engaged with the rack. To the driving shaft are secured a pulley to which the turning force from a motor is transmitted and a control wheel for manually rotating the driving shaft. A clutch member is interposed between the pulley and the control wheel. When the clutch member is engaged with the pulley, the slider is automatically moved up and down, while when the clutch member is engaged with the control wheel, the slider can be manually moved up and down. The height gauge further includes a control circuit which stops the drive of the motor when the touch signal probe generates a touch signal and which holds the indication of a measured value being displayed at that time.

Height gauge

A two-directional touch sensor for use in a height gauge, other measuring instruments or the like, wherein an abutting contact with a workpiece (W) to be measured is detectable in two directions opposed to each other at 180.degree.. The main body (1) of sensor has a probe shaft (13) rotatably supported by the main body (1) and provided at one end with a spherical measuring element (18) and at the other end with a contacting element (20). When an abutting point (18A) or (18B) of the measuring element (18) being in abutting contact with the workpiece (W) is aligned with a neutral axis (M), the contacting element (20) comes into contact with either one of electric contact points (54B) and (54A) to emit a touch signal.

Two-directional touch sensor

A displacement measuring instrument wherein a cam (9) is engaged with a movable member such as a spindle (5), a rectilinear movement of the spindle (5) is converted into a rotary motion of the cam (9), the rotary motion of this cam (9) is enlarged and transmitted to a follower through a rotator (20) rotatable in synchronism with the cam (9), an indicating device (32) is driven due to rotation of the follower (21) for indicating a displacement value of the spindle (5). Component parts are small in number and construction is simplified.

Displacement measuring instrument

A dial gauge wherein a cam (14) engaged with a spindle (16) and rotatable in accordance with an axial displacement value of the spindle (16) is provided and an indicating mechanism (13, 113) is driven by a rotation of the cam (14) to indicate a measured value. This dial gauge is simplified in construction and easy in assembling without requiring to use high precision-finish parts such as a rack portion, pinion and the like.

Dial gauge

A dial gauge wherein a mechanism for imparting a displacement of a spindle is simplified in arrangement. In this dial gauge, a link is rotated by a driving piece secured to the spindle, and a rotational value of this link is imparted to a cam member connected to a hand through a reciprocating member, so that the displacement of the spindle can be indicated.

The present invention relates to a micrometer constituted such that an anvil is supported on a frame by means of parallel leaf springs so that the displacement of said anvil may be magnified and transmitted by a sector gear to a pointer; and said leaf spring is urged toward the spindle by another spring.
